Application filed April 1, 1916.' Serial No. 88,229.

To aZZ whom it may concern lie itlrnown that l, llnwnunL. KnLLAN,a citizen oi: the llnltedtltates, and a resident of Chicago, in the county oi? Cook and Stateoi? lllinois, have invented certain new and useful improvements in fillow-Closingclvlixing-llaucetsg and I do herebydeclare that the following is a "full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the charactors of reference marked thereon, which form. a part of this specification Tl his invention relates toa novel slow closing faucet for use in connection with lavatories or other places where it is desired to a draw a certain quantity oiiwater andinsure that the faucet will not remain open and the water be'fallowed torun indefinitely after the original charge of water has been used; r g i p The device ernhodyingeny invention is adapted more especially for use'in hotel: and like public wash rooms. i

In places where water is paid torat meter rates the loss occasioned to the proprietor of such a place due to the fact that the patrons leave the faucets open. is consider- 1 able, and tor this reason, it is a general practice to. equip such places with quick closing ancets to avoid waste. a

flt is the purpose of. my. invention to provide a taucet whichwill furnish a flow of water suiiiciently long to fill a lavatory howl without niaintai ning the hand pressure on the faucet or, if desired to washthe hands in running water, to furnish a supply suflicient for this purpose, in one ioperationhof the faucet, and which Will also close after a predetermined time to prevent wastage of waterl i l The invention consists in the combination and arrangement of the pa-rtsshown in the drawings and described in the specification and is pointed out in the appended claims;

In said drawings i Figure 1 is a side elevation of a faucet embodying. my invention.

Fig. 2. is a top plan view thereof, Fig. 3 isa verticalsection ontheline 3+ -3 ofullig. 1.

Fig. i is p a horizontal section on the line lt'-..ili lll i itit edee s f t e swa piston which controls the closing movement ofthefvalve. 1 u T a il i is adetail view of one oi the shells on which one of the valve seats is formed and through which communication is had from one of the inlets oi the valve to the common outlet, assuming a double valve.

As shown in the drawings 10% designates a valve casing which, in a douhlevalve, is of ohlongcross section as shown inl igs. 2 and l. In the double form of valve the said casing-is provided with two: inlet ine nliers 11, 11, one adapted forconnection with. the hot water pipe and the other for connection with the cold water pipe, and a common out let ineniher to which connected the downtinrned discharge member-1E3. The said casinglis provided with a flange 15 which rests onthe upper face of the lavatory howl ,l6, or other part to which the fixture is Patented Jan. 18,1921.

11 extend through suitable openingsin the partlG and are screw threaded at their lower ends to receive clamping-nuts .17 be tween. which latter and the part 16 may be interposed suitable washers 18.

As herein shown the elements of one valve deviceare duplicates ofthe elements of the other valvedevice and in the following description hut onset the valve devices is assumed, except where necessary reference ismade to two like pa tsto explain the cooperation on: one sideot. the valve to the other. i e

Arranged Within the casing-1.0 are two shellsiQO, eachoi; which has a restricted lower end21. which extends into the appropriate inlet pipe l'l. and an upper enlarged .portion22 provided with a series of openings 23 which afl'ord communication between the inletipipe and the valve casing when the valve is open. Between the larger and smallerportions oi the shell 20 is formed a flat shoulder, and between said shoulder and a the floor of the casingaround the restricted portion 21 is interposed a. yielding washer 25 to provide a water tightj oint a l i 27, 27, designate. cylinders which are screw threaded at. their lower ends to engage into screw threaded apertures at the upper side ofthe valve casing; for a purpose hereinafter to be described. The bottoms of said cylinders bear upon the upper ends. oif

j the shells 20 and the screw threaded connections of the shells with the casing serve to exert a clamping pressure on the washers as will be evident.

30, 30, designate valves which cooperate with seats 31 formed on the lower ends of the smaller portions of the shells 20. Each of said valves is carried by the lower end of a stem 32 which extends upwardlyinto the cylinder 27 and through a stuiiing box formed in an extension 33 of the cylinder. The upper end of said stem'is provided 'with a head 34, between which and the follower member 35ofsaid stuffing box isinterposedv anexpansively acting spiral spring 36 which surrounds said stem, The said spring 36 serves to normally hold the valve 30 against its seat. The spring is so proportionated to the throw of the valve stem that itremains'unde'r restraint when the valve is closed so that thereby there is maintained a continuous 'spring' pressure on the yieldable body 37 ofthe stufiing box to insure a liquid tight joint-between the valve stem and the surrounding parts.

The cylinders 27 constitute parts of a timrng arrangement which operates to time the closing movements ofthe valves. They are {filled with oil or other suitable fluid; Arranged within each cylinder is a piston 40, the elements of which are shown best in :Figs. 3 and5. Said piston is carried by the lower end of a reciprocating, hollow stem 41.

which extends through the upper end of the cylinder and through a stuffing box 42 carried thereby. As herein shown the upper end or wall ofthe cylinder comprises a screw threaded cap 43 between which and the end of the cylinder is clamped a packing washer 44. The said cap has'a central, upstanding, externally, screw-threaded nipple 45 over which fits the cap46 of the stufiing box and between the outer end of the cap and the follower member of the stuffing box is interposed a spring 47 by which to maintain a constant yielding pressure on the comp50, 51,-arescrew threaded to the reduced lower end. ofa fitting 41' which latter is here shown as. screw threaded to the lower end of thefstem 41. v. j

fCommunication is aflorded from the space ;in the cylinder below tliepiston to the space therein above the piston through a bypass comprising an axlal passage which opens at the lower side of the piston and a lateral passage 56 which opens above the piston, said passages being formed in the fitting 41'.

The flow of liquid through said by-pass is controllable so as to thereby regulate the time of closing of the valve by a regulating device which is made as follows:

5S designates a rod which extends through the hollow reciprocating stein all. It is provided at its lower end with a reduced screw threaded portion 59, the terminal of which constitutes a valve to control the by-pass, composed of the passages 55, 56. Said screw threaded portion of the rod has screw threaded engagement with internal screw threads of the fitting -l-1 surrouinling the passage 55 whereby, when said rod is rotated on its axis, it is adjusted, toward or from the lateral portion 56 of the b pass so as to regulate the iiow of liquid there through. Said rod is grooved at its upper end to receive a screw driver or like implement by which it may be turned on its axis when the thumb piece 4-8 is removed to thereby adjust the by-pass valve device. In order to prevent the escape of liquid past the screw threaded end of: the rod the space surrounding the said reduced screw threaded portion of the rod within the lower end of the hollow stein 4-1 is filled with a suitable packing material 61, as shown in Fig. 3. Said packing is confined between the shoulder on the rod 58 formed between the larger and smaller portions of the. rod and the internal shoulder formed between the larger and smaller portions of the fitting 41'.

In the operation of the device, pressure on the thumb piece 48 depresses the piston 40 which in turn acts on the valve stem 32 to force the valve 30 away from its seat 31. The water, under pressure, escapes past the valve into the valve casing 10 and outwardly through the outlet 13. in order to hasten the opening movement of the valve the dimension of the cup leather of the piston 40 is such, relatively to the internal diameter of the cylinder 27, that when the piston is thus forced downwardly to open the valve 30, the liquid within the cylinder 27 is free to flow around the piston so that as the valve is depressed the liquid is displaced from the lower to the upper side of the piston. \Vhen the valve is so depressed the spring 36 is placed under compression and power is stored therein to close the valve when hand pressure is released. The closing movement of the valve under the action of the spring 36, however, is retarded by reason of the fact that the displacement of the liquid from the upper to the lower side of the piston, in the upward movement of said piston, is restricted by the bypass comprising the passages 55, 56. By reason of the regulable action of the valve 59, with respect to the by-pass, the lay-passing of the liquid iii) shown in Figs. 3 and 5, which surrounds the upper end of the fitting 4e1"and is clamped in place by means of a bellshaped clamping member 64 that has screw threaded engagement with the lower end of thestein ll and bears at its lower annular edge against a marginal flange 65 of the screenpbestshown in Fig. 5. The said bell shaped member provided with one or i more openings: 66 through which liquid may flow.

By reason of the fact thatthe by-passes of the twosides of the valveare independently regulable it will be noted that thetiming elements of the two sides of the valve may be so adjusted relativelyto each other that a larger volume of water may flow through one side of the valve than the other. It is thus practical thereforeto adjust the faucet to supplies of hot and cold water (littering in their-relative: temperatures so asto obtain as a result ofthe mixing of the hot and cold water a mixture" of adesired temperature.

Attention is also called to the factthat the operating stems and the timing pistons are made, as unitary parts, separate from the valve and their stems. This construction not only simplifies the manufacture of the valve and reduces its cost but also enables said timing pistons to be removed from the timing chambers without disturbing the set tings of the valves, thereby simplifying the cleansing of the valve and replacement and repairs of the parts associated with the timing mechanism and the replenishment of the liquid in the timing cylinder, all without shutting off the water which the valve controls.

By reason of the screw threaded connection of the timing shellsor chambers 27-.with the valve chamber 10, the valves 30 may be readily exposed for the purpose of repair or renewal by unscrewing the cylinders 27 from said casing andlifting said cylinders, together with the valves carried thereby away from the casing, the inlet openings in the floor of the casing being sufiiciently large to permit the valves 30 to pass therethrough.

It will be understood that the structural details of the valve illustrated may be somewhat varied within the spirit and scope of the claims hereto appended and that the invention is not limited to said details except as to such claims wherein said details are specifically pointed out, and as imposed by thaprior art. i i
